I am 38 weeks and 2 days.I lost my mucus plug/bloody show yesterday around 11:00am. I went to the hospital and found out I was dailated 3 cent. But, they sent me home. I have been having bad contractions in my lower back but there not as bad in the lower front as they are in the lower back. They are last 4 about a min and coming like between 5 and 7 mins. I just wont to know if im in labor and i dont know it?
